ASTM A213 T12(ASME SA213 T12) ndi chitoliro chachitsulo chopanda msoko chopangidwa kuti chigwiritsidwe ntchito kutentha kwambiri.
Zinthu zake zazikulu zophatikiza ndi 0.80–1.25% chromium ndi 0.44–0.65% molybdenum, zomwe zimaika chitsulo cha chromium-molybdenum alloy. Chimagwiritsidwa ntchito kwambiri m'malo otentha kwambiri komanso opanikizika kwambiri monga ma boiler, ma superheater, ndi ma heat exchanger.
Chitoliro cha T12 chili ndi mphamvu yocheperako yogwira ntchito ya 415 MPa ndipo mphamvu yocheperako yogwira ntchito ya 220 MPa.
UNS ya giredi iyi ndi K11562.
Botop Steel ndi kampani yodziwika bwino komanso yodalirika yogulitsa mapaipi achitsulo cha alloy komanso yogulitsa zinthu zambiri ku China, yomwe imatha kupereka mwachangu mapulojekiti anu mapaipi achitsulo cha alloy osiyanasiyana, kuphatikizaT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590)ndiT91 (K90901).
Zogulitsa zathu ndi zapamwamba kwambiri, zimakhala ndi mitengo yopikisana, ndipo zimathandiza kuyang'aniridwa ndi anthu ena.
Kuti mudziwe zambiri kapena kuti mudziwe zambiri, chonde titumizireni uthenga lero!
Wopanga ndi Mkhalidwe
Mapaipi achitsulo a ASTM A213 T12 ayenera kupangidwa ndi njira yopanda msoko ndipo ayenera kumalizidwa kutentha kapena kumalizidwa ozizira, monga momwe zafotokozedwera.
Kutentha Chithandizo
Mapaipi onse achitsulo a T12 ayenera kutenthedwa.
Njira zovomerezeka zochizira kutentha zimaphatikizapo fkupopera kwa ulster kapena isothermal, kusinthasintha ndi kutenthetsakapenakupopera kwa subcritical.

Chubu chilichonse chiyenera kuyesedwa ndi magetsi osawononga kapena mayeso a hydrostatic.Mtundu wa mayeso omwe agwiritsidwe ntchito udzakhala wosankhidwa ndi wopanga, pokhapokha ngati watchulidwa mwanjira ina mu dongosolo logulira.
Njira zoyesera ziyenera kuchitika motsatira zofunikira za Gawo 25 ndi 26 la ASTM A1016.
Makulidwe a machubu a ASTM A213 T12 ndi makulidwe a makoma nthawi zambiri amakhala ndi mainchesi amkati kuyambira 3.2 mm mpaka mainchesi akunja a 127 mm, ndipo makulidwe a makoma osachepera kuyambira 0.4 mm mpaka 12.7 mm.
Mapaipi ena achitsulo a T12 amathanso kuperekedwa, bola ngati zofunikira zina zonse za ASTM A213 zakwaniritsidwa.
Machubu opanda msoko a ASTM A213 T12 a alloy steel amagwiritsidwa ntchito makamaka m'malo otentha kwambiri komanso opanikizika kwambiri.

Amagwiritsidwa ntchito m'mafakitale opangira magetsi opangira machubu otenthetsera ndi otenthetsera omwe amagwira ntchito kutentha kwambiri komanso kupsinjika.
Amagwiritsidwa ntchito kwambiri ngati machubu a boiler m'malo opangira magetsi, m'mayunitsi obwezeretsa kutentha ndi zinyalala, komanso m'maboiler a mafakitale.
3. Zosinthira kutentha
Yoyenera kugwiritsa ntchito machubu osinthira kutentha m'mafakitale a petrochemical ndi mankhwala chifukwa cha kukana kwake kuzizira komanso kukhazikika kwa kutentha.
